DRAWER LATCH. e *ffii Application filed February 17, 1922.` Serial No.537,343. F' 2 To all fao/'wm t may concern.'

Be it known that I, OWEN MoTBY STEVENS,

a citizen of Canada, and a resident of Wallace, in the county ofShoshone and State of Idaho, have invented a new and Improved DrawerLatch, of which the following is a description.

My invention relates to a latch embodied in a handle for drawers or thelike, the general purpose being to provide alatch for a drawer that willexclude children with out the necessity of locking the drawer and yetwill enable the drawer to be unlatched and opened by adults withfacility and dispatch.

The stated object is attained by a novel arrangement of latch devicesassociated with a turnable handle bar and constructed and arranged ashereinafter described and claimed.

Reference is to be had to the accompanying drawings forming a part ofthis speciiication, it being understood that the draw ings are merelyillustrative of one example of the invention.

Figure 1 is a front elevation of a drawer handle embodying my inventionillustrating the same applied to a drawer shown in part;

Figure 2 is a horizontal section on the line 2-2, Figure 1;

Figure 3 is a cross section 3*3, Figure 2;

Figure 4c is a vertical section taken through the latch bolt;

Figure 5 is an enlarged section in a plane corresponding with the line5-5, Figure 2 and taken through the latch bolt.

In carrying out my invention in accordance with the illustrated example,a drawer handle is provided, consisting of brackets 10, 10l one of whichhas its base 11 integral with the securing plate 12, the other bracket,10, being separate from the plate 12 and having its base flange 13secured by screws 14: which pass also through said base plate into thedrawer A.

The outer ends or heads 15 of the brackets 10, 10a are hollow andopen attheir op posed inner sides to turnably accommodate and form bearings forthe ends of a handle bar 16 which is preferably knurled.`

On the handle bar at one end is an eccentrically positioned pin 17,secured to which is one end of a link 18 which extends through thehollow bracket 10, the opposite end of the link extending into a mortiseon the line PATENT OFFCE.

has a second crank 24 therein and pivotally secured to said second crankis the shank 25 of a vertical latch bolt 26 which is slidably fitted inan internally threaded boss 27 on the top 28 of the latch plate 23.

I/Vith the described arrangement the handle bar 16 may be grasped forthe opening of the drawer and given a turning movement to cause theeccentric pin 17 to rock the shaft 2l throughthe link 18 and crank arm20 and thereby through the second crank arm 24 give axial movement totheshank 25 and bolt 26 to withdraw said bolt within the plane of the top28 of the latch for releasing the drawer.

. Spring means is provided normally tending to project the latch 26 tothe latching position and at the same time restore the shaft 24E and thedescribed shaft operating means.A In the illustrated example I haveshown a coil spring 29 secured at one end to the crank arm '18 of shaft21, the opposite end of said spring being secured to a iixed `lug 30 orits equivalent at the interior of the lock. There is illustrated asecond spring 3l coiled about the bolt shank 25 and abutting at one endagainst the guide lug 32 at the interior of the lock, said spring 31abutting at its opposite end against the lflanged inner end 33 oflatchbolt 26. Either or both of said springs 29, 31 may be employed and ofsuticient strength to restore the parts.

I would state in conclusion that while the illustrated exampleconstitutes a practical embodiment of my invention, I do not limitmyself strictly to the exact details herein illustrated, since,manifestly, the same can be considerably varied without departure fromthe spirit of the invention as defined in the appended claims.

Having thus described my invention, I claim:

1. A drawer handle and latch comprising brackets adapted to be securedto the drawer, a handle bar turnably supported in said brackets, one ofthe brackets being hollow, a pin disposed eccentrically on said handlebar at one end and projecting across the bore of the hollow bracket, alink pivotally secured at one end to said pin, a shaft having a crankarm to which the opposite end of provided with an eccentrically disposedpin at one end, means to support said handle on the drawer, a latch boltfor the drawer, a crank, means extending between the holt and the crankfor imparting a movement el the latter to the former, and means betweenthe crank and the eccentric pin Whereby said crank is made to turn withthe turning of Said handle.

OWEN MOTBY STEVENS.
